Float for spectacles

ABSTRACT

A float for spectacles including a blow molded air cell made of a resilient plastic material and having a pair of integral molded loops at its opposite ends. These loops, when threaded onto the temple of a pair of spectacles, are bent out of the plane in which they are molded and resiliently press against the inside of the temple to hold the air cell in mounted position thereon.

FIG. 2 is a top plan view of a float mounted on th temple of an eyeglassframe;

FIG. 3 is a bottom plan view of the float;

FIG. 4 is a side elevation of the float mounted on the temple of aneyeglass frame; and

FIG. 5 is a vertical section taken on the line 55 of FIG. 4.

DESCRIPTION OF THE ENCLOSED EMBODIMENT Referring now to the drawings andto FIG. lin particular, there is shown an air cell which has a pair ofintegral loops l1 and 12 formed at its opposite ends. The air cell andloops are blow molded from a resilient plastic material. The wallthickness of the air cell is very thin keeping the weight of the floatat a minimum so that a pair of floats may be worn with maximum comfort.

Referring to FIGS. 3 and 5, it will be noted that a channel 13 is formedin the bottom of the float and extends lengthwise of it between endloops 11 and 12.

End loops are formed in planes substantially parallel to the bottom ofthe channel so that when threaded on a temple they are bent out of theplanes in which they normally lie and resiliently press the temple intochan nel 13. Thus loops 11 and 12 hold the float in mounted position onthe temple.

The temple shown is of the plastic library type hingedlyconnected byhinge 15 to a spectacle front 16. It

should be noted that the float may be mounted on any type of temple andthat loops l1 and 12 are so positioned with respect to channel 13 thatthey will resiliently press against the inside of any temple on whichthey are threaded.

In use, a pair of floats are mounted on the temples of a pair ofspectacles although a single float may be used on a light frame. By blowmolding the air cell and the loops as an integral complete unit, unitcost is kept at a minimum and the correct position of loops 11 and 12with respect to the air cell is assured.

As various possible embodiments may be made of this inventive concept,and as many modifications may be made of the embodiment hereinbeforeshown and described, it is to be understood that all matter herein is tobe interpreted merely as illustrative and not in a limiting sense.

lclaim:

1. In a float for a pair of spectacles blow molded as an integral unitfrom a flexible plastic material, the combination of anair cell having athin plastic wall and a pair of loops integrally formed on the ends ofsaid air cell,'said loops being resilient and lying generally. in theplane of the float and being bent out of said plane when threaded ontothe temple of -a pair of spectacles,

whereby they resiliently engage the inside of the temple to hold the aircell in mounted position on the temple.

2. In a blow molded float according to claim 1 in which a channelextends longitudinally of the air cell, said loops when threaded on atemple resiliently pressing the temple against the bottom of thechannel.
